If you need support from Yola please contact us via firstname.lastname@example.org or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
If you have several different Yola sites, you can move your paid domain name from one site to another.
If you have several domains that all point to one site, you can choose which one is the primary URL, which will appear in the web browser.
As Jean has pointed out, you can certainly keep your website, and publish it to a different domain.
However, you cannot deactivate your current domain name and replace it by a different domain name immediately. You will need to let your old domain name expire. While doing so, you can already purchase your new domain name, keep your website published to your old domain until it expires, and publish your site to your new domain as well once it is up and running. You can always publish your site to multiple domains.
Jean has given you the right link. If you need further assistance on this, please let us know, and we will be happy to help you.
